So my friend has more than one site but we own one together. We decided to split the profits for the website, but he doesn't know how to find the google Adsense clicks for that one specific website. Is there anyway to do that?
You can do that by adding channels. Note: Don't place two different adsense ad codes in the same page or else you'll get banned.
Channels! create a specific channel and use the same in all adsense codes used in that site. Actually, you can create few channels to identify the site and locations of the ads, for performance tracking. Google for more info.
Nope it not allowed good to learn from others instead of from your own mistakes (getting banned) right? that's what DP is for. Anyway, as others said, create channel(s) for that web site so you will know the earnings. Cheers.
The reason for this is that the publisher ID is supposed to belong to the person who actually owns the site. As has already been stated using channels is the way to go. There is no limit to how many channels you can use. Setup a channel for each different ad location so you can keep track of where all the clicks are coming from. This will help you to optimize your ads in the long run.
